Am I the only one lucky enough to have kernel-5.18.11-200.fc36.x86_64 crash reliably, on particular hardware, after starting a VM in virt-manager? At least I think it's a crash. One second after a VM start it's brick-city. Display frozen, no response from the network. I've got nothing: after a reboot there's nothing in journalctl -r -b -1. This brings up fond memories -- ages ago I had a null modem adapter hooked up to a serial port, the kernel configured for a serial console, thusly I was able to capture OOPSes over the serial console, in situations like these. But, these days, no more RS-232 ports. I dimly recall that a USB-serial option is possible; but I don't have any of that in any case. Anyway, reverting to 5.18.9 made this VM happy, and my VMs on another hardware, also running the same kernel, are also fine. But, 5.18.11 gets reliably clusterfarked by qemu on at least on some hardware combinations. I wish I had more useful data points, but I've got nuthin' worth putting into Bugzilla.
Just a data point for you. I run 5.18.11-200.fc36.x86_64 on the host and on the guest (KVM). No crashes so far. However, sound is now broken, highly distorted, so maybe there is something bad with this kernel? You bay want to set rsyslog to log to the host, hoping to catch messages that did not make it to the guests fs. I have all my machines log to my server (which is the host too). A special, long incantation is appended to /etc/rsyslog.conf (on the guest). On the host I Provided TCP/UDP syslog reception in the same conf file. -- Eyal Lebedinsky (fedora@xxxxxxxxxxxxxx) _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
